Atulpriya Sharma

Known across the cloud-native community as Maharaj, I make complex technology accessible - from KubeCon stages to community meetups to client boardrooms. What started as a manual QA engineering career over a decade ago has evolved into leading developer relations at scale as a Principal Developer Advocate.

With a B.Tech in Computer Science Engineering and a PGDM in Marketing, I combine engineering depth with narrative instinct - debugging a Kubernetes operator in the morning and crafting a developer content strategy by afternoon.

Speaker at every KubeCon since Chicago 2023, Co-Chair of KubeCon India 2025, Co-Chair of the CNCF Platform Engineering Technical Community Group, and organiser of Cloud Native Hyderabad.

Lianne Potter

Lianne Potter

Lianne Potter is an award-winning technologist, digital anthropologist and Co-Founder & Chief AI Security & Ethics Officer at NorthStar Intelligence. She works at the intersection of AI security, safety, ethics and human behaviour, helping organisations understand not just what their technology can do, but what can go wrong, who is affected, and who is accountable.

With a background spanning software development, cybersecurity leadership and anthropology, Lianne brings a perspective that is unusual in the technology industry. She understands the technical mechanics of systems and the human, cultural and organisational forces that shape how they are built, used and abused.

Her work explores some of the difficult questions facing technology today: how do we secure AI systems? How do we assess risk when the technology is changing faster than our governance? What happens when the language we use to describe AI obscures human responsibility? And how can we build systems that are not only technically capable, but safe, accountable and worthy of trust?

Lianne is a former Head of Security Operations for one of Europe's largest greenfield technology transformations and holds an MSc in Data Science and AI. Her research spans AI safety and the use of multi-agent conversational systems to interrupt harmful ideological trajectories, combining technical experimentation with insights from anthropology and behavioural science.

An international speaker, published author and award-winning podcaster, Lianne is known for challenging conventional thinking and making complex technical and ethical questions accessible without losing their substance. Her talks range from AI security and governance to the hidden cultural signals behind cyber risk, the politics of technological language and the lessons we can learn from science fiction.

She is Co-Host of *Compromising Positions*, a podcast asking uncomfortable questions about technology and whether we're the baddies, and *Tech Film Noir*, where science fiction meets a healthy dose of technological scepticism.

Lianne's work and commentary have appeared in publications including *The Times*, *Raconteur*, *The Yorkshire Post* and *IT Pro*. Her awards include Security Specialist of the Year and Cybersecurity Personality of the Year.

Molly Painter

Molly Painter

I've been working as a .NET developer for over 20 years now in a variety of industries including government, retail and manufacturing. But I've been hacking around with computer code since I was old enough to read my Dad's copy of the ZX Spectrum BASIC coders manual.

I've been speaking about Functional C# at various user groups and conferences around the UK, USA, Europe and Australia and am particularly interested in seeing just how far we can push C# without breaking it.

In 2023 I released my first technical book: "Functional Programming with C#", published by O'Reilly Media.

When I'm not coding, or running after my two small children, I have been known to enjoy the classic series of Doctor Who, Fighting Fantasy Gamebooks, Cryptic Crosswords, and rather more coffee than is probably good for me.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
